Abstract (en)
A spun-bond web production apparatus comprises a spinneret for producing descending thermoplastic synthetic resin filaments; receiving device for receiving filaments; continuously movable collecting foraminous belt; and at least two mutually independently controllable suction zones beneath the belt for drawing air and including a primary suction zone at which a greater part of the filaments are drawn onto the belt. A spun-bond web production apparatus comprises a spinneret (1) for producing descending thermoplastic synthetic resin filaments; receiving device below the spinneret and receiving filaments for aerodynamically stretching the filaments; continuously movable collecting foraminous belt (7) displaceable longitudinally in a web-producing direction below the receiving device to produce a spun-bond web; and at least two mutually independently controllable suction zones (11) beneath the belt for drawing air through and in succession in the web-producing direction, and including a primary suction zone at which a greater part of the filaments are drawn onto the belt and at least one other suction zone.
Abstract (de)
Anlage zur kontinuierlichen Herstellung einer Spinnvliesbahn aus aerodynamisch verstreckten Filamenten aus thermoplastischem Kunststoff, mit einer die Filamente abgebenden Spinnerette. Unterhalb der Spinnerette ist ein kontinuierlich bewegbares Ablegesiebband (7) angeordnet, auf dem die Filamente zum Spinnvlies ablegbar sind. An dem Ablegesiebband (7) ist eine Saugeinrichtung zum Ansaugen von Luft durch das Ablegesiebband vorgesehen. In Förderrichtung des Ablegesiebbandes sind zumindest zwei voneinander getrennte Absaugbereiche (10,11,12) hintereinander angeordnet. Einer dieser Absaugbereiche ist ein der Ablegezone zugeordneter Hauptabsaugbereich (11). In dem Hauptabsaugbereich (11) und dem zumindest einen weiteren Absaugbereich sind die Absauggeschwindigkeiten jeweils unabhängig voneinander einstellbar. <IMAGE>
